Specification of Letters Patent.

Patented Mav 9. 1916.

Application filed September 6, 1910. Serial No. 580,690.

To all whom it may concern Be it known that I, .VVILLIAM Nrcnois, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Time- Table Mechanisms, of which the following is 'a specification.

. This invention relates to improvements in time table apparatus and it has for an object, among other things, the production of a mechanism by which time tables and particularly those of railroads may be compared and examined.

It is a further object of the invention to supply mechanism by which old or existing time tables and new time tables may be compared, the relation of all their parts being examined and their hearing. one upon another, being determined, the conditions resulting from a change from one time table I to another, being also developed so that they can be made clearly apparent and noted.

Another object of the invention is the provision of a mechanism in, which part or the whole of a .time table may be temporarily covered as to hide from view such parts of one or more of the tables, that may become inoperative for'any reason, as for instance achange from anold schedule to a new.

It is also a further purpose of theinven. tion'to provide a time table mechanism in whichthe tables examined finay be illumi nated, either by natural or artificial means,

and may thus be used to advantage by day or by night. With these and other objects in view the invention consists in certain novel constructions', combinations and arrangements of parts, as will be, hereinafter more fully described and claimed.

In the accompanying drawings, forming a. part of this specification :-Figure 1 is a front elevation of. the improved time table mechanism, portions thereof being broken away to show some ofthe interior construction of the apparatus. F ig. 2 is a horizontal transverse sectional view taken through the" the new and old time tablesbe compared mechanism upon the line (1-6 of Fig. 1. Fig. 3. is a perspective view showing the interior of the time table mechanism, the

tary view of a .zti'me table chat I portion of one of the-curtains employed for covering a part of the apparatus. Fig. 6, is a detailsectional view of a portion of said curtain and a part of the front of the time table mechanism, showing the means employed for holding ourtain in an adjusted position. Figs. and 8, are detail views in front and side elevation respectively, illustrating an adjustable statlon indicator or pointer employed iipon the front of the apparatus. F ig. 9,.is a front elevation of a modified form. of the time table mechanism, in which of stations is used for both time tablesi'that may be compared. Fig. 10, is a vertical central section through the same. Figs. 11, 12, 13 and 14, are dia rammatical views, showing schedules as 1: used with the station, time, direction, class, and number designations on onesheet the schedules being held side by side, and illustrating the use of curtains of different {sizes and shapes, for covering portions of the said schedules and thus indicating the effectiveparts of the same on the days of change of time table.

The present invention is particularly useful in connection with railroads, making it possible to demonstrate in concrete form resulting from a change of timetables at given times. The accurate working out of es is so intimately connected with the sa ety ofthe traveling public, that it has become necessary for railroads and railroad associations, to develop certain rules governing the operation of trains and.

the bearing upon old and new'schedules, of a change to a new one, that it has become an important matter that all employees be carefully schooled in these things. I

The time table apparatus forming the subject matter of the present invention is designed for this purpose, and is well adapted to illustrate bymeansv of the related parts of the device. the consequences of making time table changes, under the rules of the railroad companies. Not only can side by side, but the efi'ective parts thereof can be ascertained and their relation to one another be determined.

The construction of the mechanism is such, that oneor more schedules may be brought opposite'each other so that the numa single line ey are sometimes p bet, class, day or days of leaving a given station, the direction of trains operable on the schedule and the initial and terminal stations can be compared at a glance, and the time when the new schedule goes into etl'ect can be shown together with its effect upon the trains of both schedules.

The principal features of each schedule may be carried on a single strip or sheet of material as shown in Figs. 11, 12, 13 and 14, and the said schedules in this form may be hung or placed side by side, for comparison, but the invention is generally embodied in mechanism like that illustrated in Figs. 1, 2, 3 and 4 and the said invention will now be more fully described, reference being bad to said figures. As shown in the drawings, the time table apparatus comprises a casing, housing or closure 1, the front wall of which is provided with a number of apertures through which the schedules may be made apparent. Within the housing 1 and to the rear of the perforated front are mounted a schedule time strip or scroll 2, one or more station strips or scrolls as 3, a strip or scroll capable of showing the class, number and frequency of the schedule as at 4, as well as other strips or scrolls as 5, indicating the numbers of the time tables.

The scroll strip 2 is made up of a strip or band of flexible material, preferably of a semi-transpa rent or translucent character, as for instance tracing linen or some similar material, which will permit light to shine through from the rear or interior of the apparatus and yet not reveal the inner-structure of the housing 1. The said strip or band of material 2, is made of ample length to contain or have marked, painted, printed or otherwise placed on the face thereof, columns of indications, showing the times when trains are due and authorized at various stations. The scroll strip 2 is wound upon vertical rollers 6, 6, which are arranged within the housing 1, preferably in the front corners thereof as shown in Figs. 1 and 2. The journals of the rollers 6 (i, have bearings as at 7 and 8 in the structure of the housing. One of the journals of each roller 6, preferably the lower one is extended beyond its bearing and carries a beveled gear 9, which meshcs with an actuating pinion 10, carried by and actuated by an operating shaft 11. Each shaft 11 projects through the front wall of the housing 1 and is provided with a crank 12, by which it' may be turned. By turning one crank 12, the scroll strip 2 is caused to Itravel transversely in theapparatus behilu the perforated front, it b ing wound up ori the roller 6 thus actuated and unwound from the other roller to a corresponding degree. The operation is reversed of course by turning the other roller 6 when the scroll strip is to be made to travel in the opposite direction. The said scroll strip 2 is provided with spaced columns of time indications, as 13 and 14, which are adapted to be stopped opposite apertures or open ings15 and 16, in the front wall of the housing 1. The openings 15 and 16 are arranged in horizontal alinement with apertures or openings 17 and 18 through which appear the names of the stations passed by the trains operated over the schedules. These stations have been-indicated for convenience by the letters of the alphabet from A, to H as shown in the drawings, each of said letters indicating a station. These station indications are carried by translucent material like that of the scroll strip 2 and may be fixed or movably arranged as referred behind the openings 17 and 18. he said station indications are generally carried however by vertically moving scroll strips, as 3, 3, which are wound upon upper rollers 19 and 20 and lower rollers 21 and 22. In this way schedules over different divisions of a road, or over subdivisions thereof may be shown and examined, and changes in routes may be displayed. Each of said rollers 19, 20, 21 and 22 is connected by intermeshing beveled gearing with a crank shaft the crank ortion of which extends outside the-housmg, the said crank shafts being designated respectively by the numerals 28, 24, 25 and 26, by which the station strips 3, 3, may be rolled and unrolled and caused to travel up and down, to bring the desired stations into view through the openings 17 and 18. The station strips 3 are arranged to move in front of the transverse time strip 2 so that they will not be hid by said time strip. The

arrangement is such that the time strip can be. adjusted for bringing new columns of time indications into view to one side of the station indications, without affecting the station strips. The station strips can also be adjusted irrespective of .the time strip.

The columns of time indications upon the strip 2 are preferably arranged in pairs, each pair being made up of one column giving the time indications for the various stations on the old schedule and the other column giving the time indications for the new schedule. The spaces between the said columns come behind the station strips 3 and do not therefore interfere with them in any way, nor do the said station strips 3, cover any indications or data upon the time scroll or strip 2.

Just above the time strip 2 is arranged a similar strip 4, which may be termed the class or day strip. This strip 4 is arranged to move transversely of the housing 1, .behind openings 28 and 29 in the front there of and passes around rollers 30 and 31, arranged in the opposite front corners of the said housing 1, above the rollers ,6, 6. A transverse bar 32 mounted in the housing. carries the journal bearings 7 of the rollers 6, and also supports bearing brackets 33 which engage and movably support the lower ends of the idlcrs and 31. The upper ends oi the said idlers are journalcd in similar brackets 34 secured to the side walls of the housing 1. The endsas at 27 of the said strip 4. are wound upon rollers 52.: and 36, which are journaled in suitable brackets as 47, 47. and 48, 18 or other suitable supports arranged in the rear part of the housing near the opposite corners there- .l', as clearly shown in Figs. 2 and 3. The trip 4 is formed of translucent material, so that words, numbers or other indications of an opaque character, printed, painted or otherwise placed thereon, will show forth in trong relief when natural or artificial light s permitted to shine through the front openings of the housing 1, from the rear or interior thereof. The front surface of the said strip 4, is provided with columns in multiple, preferably in pairs, the said columns usually indicating as shown in Fig. 1, of the drawing, the class, the number of the schedule and the day or days upon which the trains of the schedules compared are run. Actuating shafts 37 and 38 extend from the front of the housing 1, back to the lower ends of the rollers and 36. they being conncctcd with the said rollers by beveled gearing as at 39 and 4.0. The said shafts 37 and 38 are provided with cranks 41 and 4-2 outside the housing by which they may be turned. By the operation of these cranks the st: ip 4 can be moved back and forth in the housing 1. to bring different columns of indications thereon, showing the class. train or schedule number, and days of running the trains. opposite the openings 28 and 29 in the front of the housing. To one side of these openings 28 and are larger openings 43 and 44. in which are made to appear the time table numbers. and below these are smaller openings -15 and 46 in which the words. Stations are usually arranged to appear referring to the columns of station names below which are seen through the openings ii and 18. The designations appearing in t 4- openings 43. 44, and -16 may be mounted on srmi-transparcut or translucent 1E! zlcrial so that the light may shim through them as in the case of the strips :3 and l. :ilreadv des ribed and said n'mlerial may be fixed in position behind said opci'iings. but

is generally made mow able, the material being in the form of traveling strips or bands 5. 5. which are wound around upper rollers 49 and 50 and lower rollers 51 and 51?. These strips f. 5, are quite similar to the station strips heretofore described and their rollers are each capable of actuation by means of crank shafts and inter-meshing beveled gears as at 53. 5 43:; and 56. the crank portions of said shafts being arranged outside the housing. These time table number strips 5, 5, extend in front of and across the transversely arranged class strip 4.

Above the class strips and the time table strips, elongated openings 57 and 58 are arranged in the front of the housing 1 and behind these openings and inside the housing is journaled a rocking member 59, the said rocking member extending transversely of the housing and being journaled therein at 60 and (31. The rocking member is preferably formed with two flat faces, as 62 and 63 upon which words indicating the direction of the schedule or train are mounted, upon translucent materia The ends of the rocking members preferabl extend at right angles to the faces 62 an 63 and support them upon the journals at 60 and 61. An actuating arm or lever 64 is secured to one end of the rocking member and a draw bar as. pivoted thereto, extends outwardly through an opening in the front wall of the housing 1 where it is provided with a handle 66. Notehes as at 67 in said bar are adapted to engage the front of the housing in such a way as to lock the rocking member in its adjusted positions. By operating the rod 55 the rocking member may be so moved as to bring different direction indications, as for instance, Eastward or Westward, etc... opposite the elongated openings 57 and 58. I

Above the elongated openings 57 and 58 are similar elongated openings 68 and (i9 behind which a rocking member 70, like the rocking member 59 just described, is journaled in the housing, its flat faces 71, 72, carrying indications which show whether the time tables are old or new. The words Old or New are mounted upon translucent material so that light shining through from the interior of the housing, will bring out the said words in bold relief. The rocking member 70, is provided with an arm 73 and an operating bar 74 in all respects like the bar 65 and the arm 64 already described. The said bar 74 is likewise provided with locking notches 75 and a handle 76. The rocking members 70 can thus be rocked back and forth to bring its flat faces with their indications, opposite the elongated openings and 69.

Above the openings 68 and 69, are elongated openings 77 and 78, in one of which the words ffew time table effective, is generally made to appear while in the other. the time when the new time table is effective is indicated. In both instances the words and indications are placed preferably upon translucent material. so that light shining through it from the back, brings out the lid words and indications in bold relief. In the of the material at the opening 77. it'is usually fixed in position there being no need ordinarily for making it movable. As

the time when a schedule becomes effective, is changed from time to time, the material opposite the opening 78 is preferably made in the form of a strip or scroll band, carrying as many time indications as desired, the said strip being rolled upon rollers 79 and 80, mounted inside the housing 1. Actuating shafts 81 and 82, carrying cranks 83 and 8-l are connected with said rollers, by inter-meshing beveled gearing, whereby the strip of material may be adjusted with respect to the opening 78, in the giving the time when the schedule goes into effect.

It will be observed that by the arrange ment of transversely and vertically moving strips, operable in a given relation to each oth r, old and new schedules, or different divisions of the same schedule, may be brought in such relation to each other as to compare all the features of one with those of the other. Also a change in one may be made to show results brought about thereby, said results affecting one or both of said time tables.

Under the existing rules of the railroads, an old schedule is often effective for a part of its time or until a train run thereon reaches a given station, and frequently a train that is able to run part way upon an old schedule, may be able to assume a part of the new schedule, after the new schedule becomes effective and thus complete its run according to such new schedule. In order to assist the eye in following the movements of trains under these and other c0nditions, the apparatus embodying the invention. isprovided at suitable points upon its front face with movable indicators as 85 and 86. These indicators are arranged to move or be adjusted upon bars or rods 87 .and 88, preferably fastened on the housing 1, in vertical positions between the stations indicated on the station strips, and the time periods indicated on the time strips, as clearly indicated on Fig. 1. As shown in the detail v-iews Figs. 7 and 8, each of these indicators ,preferably consists of. a short sleeve 89, capable of sliding on its supporting bar or rod and a clamping or thumb screw 90, by'which it can be set and held opposite any station desired. An arrow or suitably shaped pointer 91, is carried by each sleeve and clamp screw. Thus when a train is authorized to run on the old schedule to a certain station, that station can be shown upon the apparatus by moving the indicator or pointer 85, to a point on the rod 87 opposite said station. If the train can also assume the time of the new schedule at a given station that station can be indicated to the eye by bringing the pointer 86 to a position upon the rod 88 opposite said station. This arrangement is found in practice to very materially aidthe time table student in mastering the actlons of trams that are able to run upon old and new schedules before and after the time of change from one to the other.

As a further helpful aid in demonstrating and teaching the relations of new and old schedules or different parts of the same schedules over different divisions or subdivisions of a railroad and the actions of trains operated upon such schedules it is found advantageous to be able to adjustably cover a part or parts or the whole of a schedule or schedules. For this purpose the apparatus is provided at suitable points with curtains which can be drawn out over certain parts of the front of the housing. Any number of curtains of the same or of different widths or shapes may be employed as found desirable within the spirit of the invention. In the illustration herewith a plurality of such curtains are shown mounted at both the top and bottom of the apparatus. Thus curtains as'92, 93 and 94 may be mounted in brackets 95 and 96 at the top of the housing 1. These curtains are carried by spring actuated rollers, preferably of the type generally used for window shades and in order to bring them quite close to the front surface of the housing 1, they are made to pass respectively behind idlers 95, 96 and 97 which are also journaled in the brackets 95 and 96. Any one of the said curtains may thus be drawn so as to cover all or a portion of the front of the housing 1. As before intimated the curtains may be effectively made of different shapes, thus as shown in Fig. 11 curtain 92 may be made of the full width of the front of the schedule indicated on the front of the apparatus. Curtain 93 may be made quite narrow so as to cover only apart of one schedule, while curtain 94 may be made for a part of its length of a width equal to part of the time indications and for the remainder of its length of a greater width so as to cover all of the time indications.

It is also found useful to employ a plurality of curtains at the bottom of the lions ing there being shown in Figs. 1 and a of the drawing, three curtains as at 98, 99 and 100. These curtains are like those at the top mounted on proper spring actuated rollers of the self acting type and are directed in close proximity. to the face of the housing by guide rollers or idlers 101, 1.02 and 103, all of said curtain rollers and idlers being journaled in brackets 104 and 105 secured to the housing 1. These curtains are made to cover all or part of the schedules by draw.-

ing them upwardly to the proper heights.

The lower curtains like the upper ones may be made of varying widths and shapes. Thus for example curtain 98 may be made wide enough to cover both schedule columns. Curtain 99 is preferably narrower so as to cover only one schedule column while curtable to station D to thin 100 is made wide enough for a part of its length to cover the time indications of one schedule but narrower for the remainder of its length for covering only a portion of said time indications.

All of the curtains are provided with fasteners on their outer edges which are preferably in the shape of rings or eyes as 106 which are capable of engaging projections or detents arranged on the front wall of the housing 1. The detents for holding the upper curtains are preferably downwardly inclined pins lOTmounted at suitable intervals in the material of the housings front wall. Similar upwardly projecting pins or detents 108 are mounted on the front of the housing to secure the lower curtains. These detents are generally arranged opposite each of the stations indicated on the station strips.

The full width curtains as 92 and 98 are useful in covering the entire width of a schedule to a given station so as to indicate how far a train is authorized to travel upon the old. schedule and when it may assume and move upon the time of the new schedule. Thus as shown in Fig. 11 curtain 98 which covers the lower part of the old schedule shows that train N o. 1 is authorized to move as far as station D on the old schedule before the change of time table becomes effective, say at 12.01 A. M. At the same time curtain 92 may be set to cover the new time indicate that the train mav wait for the new time at D and assume the time of the new schedule for the remainder of its run. Of course it will be understood that either curtain may bepulled to cover its entire schedule when either the old or the new schedule is rendered entirely inefi'ectiveupon the day of the change of time table.

The curtains 99 and 93 are useful when the rains arerun in sections, the said our-- tains being of such a width as to cover the second half and first half respectively of the old and new time tables and by this means as shown in Fig. 12 when a train is run in two sections and the first section completed its run for the day, before the new time table became effective. it is authorized to run upon the old schedule. The second section, however, mav not have left the initial station A before the new time table went into effect in which case as indicated by the curtain 93 which leaves the second half of the new schedule uncovered, the second section of the train can assume the time of the new schedule throughout its run on the day of the change of the time table.

The curtains 100 and 94, are used to designate the runs of trains operated in sections where one of said sections may be able to make its entire run on one of the schedules whereas another section must make its run partially on the old schedule and partially through the on the new. Thus as shown in Fig. 13 the upper narrow portion of the curtain 109 is set to cover one half the time spaces opposite stations F. G and H leaving uncovered the other half of the spaces opposite F, G and H and all of the spaces opposite stations A. B, C, D and E, thus indicating that the first section of train No. 11 (it being operated in two sections) can make its coniplete run on the old time table before the change to the new is effected and the second section mayrun upon the old schedule until it reaches station E. The curtain 94 is set so that its widest portion covers the full width of the time spaces opposite stations A. B, and D, while its narrower end projection 110 covers half of the time spaces at E, F, (l and H. In this simple manner it will be made plain that the first section of the train which fulfilled the schedule on the old time table cannot run on the day of change, on the new time table and the second section which has fulfilled its run on that day,. on the old time table as far as station E, can only operate on the new time table for the remainder of its run, that is to say, from station E to station H.

The curtains of the shape of 94 and 100 are also useful in showing the operation of a train running in three sections. Thus as shown in Fig. 14, the first section can make its entire run on the old schedule and does not operate upon the new at all. The second section runs upon the old schedule from A to E and on the new schedule from E to H, while the third section does not run upon th. old at all, but assumes the time of the new schedule and runs thereon from A to H. It will thus be evident that the curtains de scribed are capable of various adjustments to show the effective portions of schedules under varying conditions and relations as existing between the schedules and the trains run thereon, whether in sections or as a single train. The curtains thus cooperate with the time strips and the station strips in demonstrating the different train relations developed by the use of certain schedules and the change from one to another at given times.

While it is important that the time, station and other scrolls or strips used in the device he made of translucent material, the curtains are preferably more opaque and can be made of material which will intercept a part or all of the light that ordinarily passes said scroll strips. In practice it is found very convenient to employ colored curtains and they are generallv made of a red color so as to be easily distinguishable from other parts of the mechanism.

The indicators or pointers 85 and 86 may also be used in connection with the curtains to point to stations where a train stops using one schedule or begins upon another and the arrows of said indicators may if desired be turned to show the direction in which a train is moving. The said indicators and 86 are also useful in showing the action of an opposing train, that is to say, a train running over the same line in an opposite' direction to the train of the schedule ex amined. The said pointers may be set to show where the opposing trains should meet or may be used to indicate the position occupied by the opposing train with relation to the schedule under consideration at the time of change of time table. It will thus be evident that the parts of the mechanism are admirably adapted for working out and demonstrating in a form easily understood by the employees of a railroad or others, all the different combinations of circumstances and positions developed in the running of trains according to authorizing schedules, put forth under the rules of railroad associations generally.

\Vhile natural light may be admitted through the back of the apparatus to illumi nate the different indicating strips or scrolls and other surfaces. upon which the letters, words and numerals. of an opaque character are aflixed, so as to show said characters in hold relief, the housing is also provided with artificial light producing means interiorly arranged. Thus electric lights at one or more points as 111 may be arranged within the housing 1. gas burner as 11). may also be arranged in the housing for use where electric lights cannot be operated. The inner surface of the back of the housing may be provided with any highly polished surface to afford a reflecting means behind the lights. By the use of the artificial lights the mechanism is rendered as useful at night as in the day time.

\Vhile the mechanism is preferably constructed with two station strips and a set of openings is provided for each as heretofore described, a single station strip and openings therefor may also be used in connec-' tion with the time strip within the spirit of the invention. Such an embodiment of the invention has been illustrated in Figs. 9 and 10 of the drawings. As shown in these views, the housing 113 is provided ,with a central set of openings vas at 114 through which are made to appear the names or in dications for the stations of the schedules. to be compared. ()n the right and left of the column of stations are columns of openings 115 and 111' for the time indications showing when trains are due at the different stations on the schedules. The time indications are carried by a transversely moving strip or band 117 which like the strip 2 above described carries columns of time indications in pairs so located as to register with columns of openings 11:") and 116 and the said strip is rolled up at its ends upon rollers 118 and 118". lrank shafts 119 and 120 project from the said rollers to points outside the housing I. so that by operating the crank portions thereof the strip 117 may be made to move back and forth behind the openings 11? and 111' so that the desired time indications may be caused to show through them.

station strip 1'31 carries the names or indi ations, as the letters of the alphabet as A to 11. for the stations of the road and is arranged to move vertically in front of the strip 117 and behind the openings 114. The ends of the strip 121 are wound upon actuating rollers 122 and 22), which are provided with the usual crank means extending outside the casing as at 124 and 125. The said strip 121 also passes over an idler roller 1213 to prevent its engaging the upper edge of the time strip 117. It will be apparent that by this structure one set of station names or strips carrying the salne may be used for a plurality of time schedules. 'lravcling indicators as 1157 and 127 are also provided on the front of the housing for indicating howfar a schedule may be operable on the day of the change of a schedule. These indicators or pointers are movably mounted on the rods 12% and are preferably similar to the iiulicators or pointers H3 and W1 heretofore described.

Above the time strip 117 is another strip oi scroll band as 1;!!! mounted upon actuat ing rollers 12111 and passing around idlers 12H inside the front of the housing. The

rollers 1210 are provided with operating (rank shafts 1:12 which extend outside the housing 113 at the bottom. The said strip 12!) passes behind openings and 1 -54 in the front of the housing and arranged above the time openings 11.) and 116. This strip 129 is provided upon its front face with columns of indications designating whether the schedule is old or new and giving the class and the number of the train or schedule and whether the train is a daily or not. hcse designations or words are arranged in multiple columns on the strip 12.) so that old and new schedules may be compound with each other. Passing in front of the central portion of the strip 12!) is a vertically movable strip 133 which is adapted to be wound upon upper and lower rollers 131' and 137 respectively. The said r llers are provided with actuating cranks 138 and 139 which extend outside the housing. The said strip carries designations and words telling hen the new time table is effective giving the hour and the day and these designations arespaced so as tocome behind and register with a column of openings in the front of the housing as at 141), the said column preferably occupying the space be tween the columnsof openings 133 and, 1 1-1..

The modified form of. the mechanism as l'ct illustrated in Figs. 9 and 10 is also provided with curtains as H1 at the top of the housing and bottom curtaim as Hz w ich are in all respect similar to the curtail: 9:2. 93. 94. 98. 99 and 100 as alreadv (lescrihed with respect to the preterred i'oim of apparatus and like them. are adapted t he drawn over portions of the face of the housing to cover inell'ective parts of the schedules at the time of the change of time table. lletents H 5 and ill are also pro vided on the front of the housing tor holding the curtains in adjusted positions. 5-inch an apparatm may have an opening at the hack as at lit and may he provided with electric lights HT and a gas hurner ll". s that the interior ot the housing mav he illuminated w either natural or art ai light. The various strips described are all preterahlv made of translu ent material a.\.
